Electromagnetic
fields (EMFS) are constantly present. The earth has its own magnetic field,
aligned to the North and South poles, and even human body cells have subtle
magnetic forces. Conventional medicine utilizes electrical equipment to
generate EMFS that influence the body's natural electrical currents to promote
healing. Complementary practitioners claim that ordinary magnets can also do
this, and use devices such as magnetic wrist bands and beds to treat illness,
particularly bone disorders. Magnetic therapy is not yet well established in
the West, but is popular in Japan and eastern Europe.

| HISTORY
The
therapeutic benefits of magnets are said to have been known to ancient Greek,
Egyptian, and Chinese doctors; Cleopatra allegedly wore a magnet on her head to
retain her beauty. Aspects of the modern therapy can be traced to the work of
the 18th century Viennese physician Franz Anton Mesmer, who argued that magnets
could enhance "animal magnetism," a universal force that he claimed
permeated the body. Mesmer's methods, such as holding a metal wand over his
patients, were dubious, but his ideas about magnetic poles were influential.
Magnetic
therapy, also known as magnetotherapy or biomagnetic therapy, is popular today
in Japan and eastern Europe. So far, it has not become well established in the
West. However, strong EMFS, generated by electrical devices, are now being used
in conventional medical practice in the US, UK, and Australia, for example by
orthopedic surgeons to heal fractures. Magnetic resonance imaging, which uses
EMFS in diagnosis, is considered superior to and safer than X rays.
EVIDENCE & RESEARCH
Clinical
research on the benefits of certain types of EMF is growing. A 1996 study in
The Lancet found magnetic stimulation of the brain helped treat depression. In
1959, American surgeons discovered how to regenerate severed amphibian limbs
using EMFS and developed this to heal human bone fractures. A 1990 University of Hawaii study found EMFS helpful in
treating osteoporosis. Surgeons in the US
and UK
use EMFS to treat fractured bones, nonhealing wounds, edema, and deep vein
thrombosis.
Conventional
medicine recognizes the potential of strong EMFS, but with no evidence that
weak magnetic fields can treat disease, doctors feel that magnetic devices are
mostly little more than placebos. CONSULTING
A PRACTITIONER
According
to practitioners, iron atoms in the red corpuscles of the blood respond to
magnetism. When a magnet is placed on the patient's body, blood flow through
the area is enhanced. This is said to improve the supply of oxygen to cells,
stimulate the metabolism, and help in the elimination of waste products.
The
therapy is more often practiced as a self-help treatment, using ordinary
"static" magnets with weak EMFS. Products such as magnetic shoe
insoles, straps, mattresses,
pillows,
and car-seat covers are available. The practitioner may show you how to use
them, or you may receive instruction from the equipment manufacturer or
supplier. A practitioner would try to choose the most suitable treatment for
your needs.
"Supermagnets,"
for example, are supposed to emit a higher magnetic force, and should be
positioned on specific parts of the body, often over lymph nodes or acupuncture
points. Practitioners may also suggest electrical devices that emit pulsating
fields at specific frequencies to target particular areas of body tissue. Such
devices include beds, special belts, and cylinder-shaped machines in which you
sit.
The
length of a treatment session varies according to the type of magnetic device
used and can be anything from a few minutes to several hours.
